function varargout = filter_panel(varargin)
% FILTER_PANEL MATLAB code for filter_panel.fig
%      FILTER_PANEL, by itself, creates a new FILTER_PANEL or raises the existing
%      singleton*.
%
%      H = FILTER_PANEL returns the handle to a new FILTER_PANEL or the handle to
%      the existing singleton*.
%
%      FILTER_PANEL('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in FILTER_PANEL.M with the given input arguments.
%
%      FILTER_PANEL('Property','Value',...) creates a new FILTER_PANEL or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before filter_panel_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to filter_panel_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
